Asides from proper fit there really isn't anyway to screw up this look, its just black on black. Although this look isn't liked here its very hard to get wrong because theres no color clashing you have to worry about etc.

Where does disdain of black suit black shirt on this forum come from???

You can search for more specific information, but I will attempt to summarize: black suits should generally not be worn for business, and should be avoided during the day. At night, some consider them acceptable. A black shirt is universally regarded as awful. It creates no contrast with the (usually) dark suit (black or otherwise), and the different-but-similar shades of black (pure black is impossible) look terrible together. They are usually worn (horribly) by people who are trying to be trendy and "fashion foward."
